This Small Business Innovation Reseach (SBIR) Phase II research project will develop an RFID system with sensor tags. This work focuses on design and implementation of a custom CMOS integrated circuit which contains hybrid analog-digital circuits on a micro-power tag. The biomedical application is vital signs monitoring including heart and lung sounds. The sensor tag operates within an RFID environment. Micro-electromechanical systems technology is used to fabricate an optimized sensor together with CMOS circuitry on the RFID-compatible tag. Heart sounds are presented as time-varying waveforms and processed algorithmically for feature extraction. Micro-power designs are used throughout the planned system. The commercialized product with disposable tag sensors can replace the jungle of wiring currently used with direct-wired sensors or, for wireless pods, the need to replace batteries frequently. The system provides a patient monitoring capability that is very convenient, highly-cost effective, capable of chronic use, and does not interfere with nearby heart pacers. The ease of application makes this system ideal as a teaching tool for medical students and specialists with both visual waveforms and sound presented to the operator simultaneously. The system will be used in hospitals, clinics, medical offices, and for outpatients in the home.

这个小型企业创新研究（SBIR）第二阶段研究项目将开发一个带有传感器标签的RFID系统。本工作的重点是设计和实现一个定制的CMOS集成电路，其中包含混合模拟-数字电路的微功率标签。生物医学应用是生命体征监测，包括心脏和肺音。传感器标签在RFID环境内操作。微机电系统技术被用来制造一个优化的传感器与CMOS电路的RFID兼容标签。心音被呈现为时变波形，并被算法处理以进行特征提取。微功率设计在整个计划系统中使用。带有一次性标签传感器的商业化产品可以取代目前使用的直接有线传感器的布线丛林，或者对于无线吊舱，需要经常更换电池。该系统提供了一种非常方便、高成本效益、能够长期使用并且不干扰附近心脏起搏器的患者监测能力。易于应用使该系统成为医学生和专家的理想教学工具，同时向操作员提供视觉波形和声音。该系统将用于医院，诊所，医疗办公室和家庭门诊病人。
